PNEUMATIC ACTUATOR ST

Description

MT Series rack & pinion pneumatic actuators continue the Max-Air tradition of easy integration, flexible customization, and reliable operation. Features include two ISO bolt circle patterns drilled directly in the body, NAMUR standard mounting for accessories, and our patented ±10° adjustment for the open/closed positions, all backed by the best unlimited cycle life warranty.

Tecnical description

• COMPACT DESIGN: The MAX-AIR rack & pinion stainless steel pneumatic actuator provides linear torque output in a compact design utilizing the same body and end caps for double acting and spring return units
• AISI 316: all external components (body, end caps, pinion and fasteners) are made in stainless steel (CF8M or AISI 316) for a superior corrosion resistance
• NAMUR: NAMUR VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners
• DEGREE OF TRAVEL: The standard angle of rotation is 90°. ST15 and upper sizes feature a travel stop with ± 10° in both open and close directions (International Patent)
• MULTIPLE OUTPUT SHAFTS: The female pinion drive is standard with a double square output drive, and optional with a double-D drive, keyed drive or custom designs to meet your specific requirements
• HIGH CYCLE BEARINGS: Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle applications
• PINION: The pinion teeth are engaged for the full length and stroke of the piston. The pinion height allows manual override without disturbing the indicated positions
• HIGH VISIBILITY POSITION INDICATOR: External open/close indicator is standard
• HIGH CYCLE LIFE WEAR PADS: Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings
• ANTI-BLOWOUT SYSTEM: ST series pistons feature a keyway as antiblowout system
• PRE-LOADED SPRING CARTRIDGES FOR SAFETY: Epoxy coated special steel springs are pre-loaded with non metallic materials. The stainless steel end caps fasteners are extra long to allow for spring relaxation
• OPERATING MEDIA: Air pressure operation from 2 to 10 Bar (40 – 150 PSI). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator
• FASTENERS: All fasteners, screws and bolts made in AISI 316 / A4
• LUBRICATION: All units are permanently lubricated at the factory with non-silicone grease
• TRACEABILITY: All units are externally labeled with a progressive serial number for traceability
• QUALITY: 100% of all units are factory pressure leak tested, and individually boxed for shipment.
